The Battle of Tora Bora was a military engagement that took place in the cave complex of Tora Bora, eastern Afghanistan, from December 6–17, 2001, during the opening stages of the United States invasion of Afghanistan. It was launched by the United States and its allies with the objective to capture or kill Osama bin Laden, the founder and leader of the militant organization al-Qaeda. Al-Qaeda and bin Laden were suspected of being responsible for the September 11 attacks three months prior. Tora Bora (Pashto: تورا بورا; Black Cave) is located in the Spīn Ghar mountain range near the Khyber Pass. The U.S. stated that al-Qaeda had its headquarters there and that it was bin Laden's location at the time.
